You don't say what units you're using for the measurements - However, the answer is 288 units (whichever you use)
6 feet or 36 inches.
2 and 2/3 yards.
Two yards of fabric is equivalent to 6 feet in length. The width of fabric can vary, typically ranging from 36 to 60 inches. Thus, a piece of fabric that is 2 yards long could be 72 inches long and anywhere between 36 to 60 inches wide, depending on the type of fabric. This allows for various applications in sewing, crafting, or upholstery projects.
I just bought some fabric to cover a glider rocker and ottoman and i bought 2 1/2 yds of 56" wide fabric. You could get away with buying 2 1/4 yds of 54"-56" wide fabric.
36 inches is 1 yard and so 2 times 1 = 2 square yards
72
36
1-3/8 yard + 2-1/8 yard = 3-1/2 yards x $5.39 = $18.87 ----
18 ft * 18 ft * 2 inches = 6 yards * 6 yards * 2/36 yards = 2 cubic yards.

You can do this but the best thing is to cut a slit, dig a hole and put in your plant. After doing all the planting cover the visible fabric areas with mulch. I'm not a great fan of the fabric covers as a weed preventor because weeds (also Bermuda grass) will grow INTO the fabric making it difficult to remove. Best weed restrictor is 2 ins. of mulch.
